FLOPS stands for "Floating Point Operations Per Second." It is a measure of a computer's performance, particularly in tasks that require complex calculations, such as scientific simulations and graphics processing. The higher the FLOPS rating, the more calculations a computer can perform in one second, indicating better performance for demanding applications. FLOPS is often used to compare the capabilities of different computing systems, including supercomputers and high-performance computing clusters. For example, a supercomputer with a rating of several petaflops can perform quadrillions of calculations per second, making it suitable for tasks in fields like climate modeling and genomics.
